No, I don't like that. The pin is made out of good stuff I'm sure, but I wouldn't put a big side load on it. It looks like the side of the counterweb should rotate CW (with the piston moving up some from BDC) enough to allow clearance to fully seat the pin......but a photo isn't the same as the real thing, and we don't know the Zetec varient in the photo. I hate quessing. Have you tried the short pin? You can't find a nice small, bright LED torch (or MAG light), and mirror, and have a peek? No Euro Zetec experts around? So the flywheel lock definitely isn't useable?
